Member Rewrite Error??

Upon clicking on a new register user, Im seeing the "User profile does not exist error"

You can view his picture and everything inside the AdminCP, but i've figured this much out:

His username: SmokingD's04

When you click on his name from the Memberslist, It displays his profiles correctly.

But, When the user post and you click on his name, then click view profile.

It reads the "The User has not registered, etc..."

I found in the url of the error message:

HTML Code:

The Correct URL that works off of the Memberlist is this:

HTML Code:

http://www.dieselhaulin.com/forums/members/smokingd-s04.html

Why is the URL's different? I see where the "-" is missing in the error url.

Since his name has a " ' ". Why would it be changing?

Fixed..
